Karol Stanisław Olszewski (b.
January 29,
1846 in
Broniszów -
March 24,
1915 in
Kraków) was a
Polish chemist,
mathematician and
physicist.
In
1883 Olszewski,
Zygmunt Wróblewski and Karol Sitarski were the first to
liquefy oxygen,
nitrogen and
carbon dioxide from the atmosphere in a stable state (not, as had been the case up to then, in a dynamic state in the transitional form as vapour).
Olszewski studied at the Faculties of Mathematics and Physics, and of Chemistry and Biology at the
Jagiellonian University. He carried out his first experiments using a personally improved compressor, condensing and compressing
carbon anhydride (
dioxide). He defended his doctoral dissertation at
Heidelberg, after which he returned to his parent university, where he obtained the title of extraordinary professor.
